Blood-pressure Sensor System

There is provided a blood-pressure sensor system wherein a blood-pressure sensor including a plurality of structures which induces surface plasmon resonance on a light-receiving plane of a photoelectric conversion element is attached to an outer wall of a blood vessel, in which if the blood-pressure sensor is deformed according to expansion or contraction of the blood vessel, an interval of layout of the structure is changed (widened or narrowed), so that an incident form of light with respect to the structures is changed to cause the output from the photoelectric conversion element to be changed. The output is measured as an open circuit voltage, and index calculation is performed, so that a blood pressure value is measured.
